The present star is in the late stages its life as Polaris. In the Roman Era, the North Pole was more or less equidistant from Kochab and the present Pole Star. In the year 3000, Alrai will be closer to the Celestial Pole and the present star will cease to be Polaris.
Polaris is a type of star known as a yellow supergiant. It has likely already passed the midpoint of its life cycle and is currently fusing helium in its core. In the future, it will eventually exhaust its fuel and undergo a supernova explosion, which will mark the end of its life cycle.
It is a red dwarf
What is capella star life cycle
The "star life cycle" refers to stars. Earth is not a star.
No. Life cannot exist on a star; stars are far too hot to support life. There are no known planets in the Polaris system and the output from Polaris A is probably too variable for a stable environment.
No, a protostar is basically the BEGINNING of a star's life cycle.
The north star, Polaris (aka Alpha Ursae Minoris), is a fairly large, bright star, about 430 light years away. It is an F8 supergiant, six times the mass of our sun. This star will complete its life cycle in much less than time than our own sun will.
Polaris, also known as Alpha Ursae Minoris, will become the North Star again in 27,800 AD. The cycle takes about 25,770 years to complete. Polaris is the current North Star. Polaris replaced Thuban around the first millennium BC. It will become closest to the celestial north pole around the year 2100 and start moving farther away. Gamma Cephei, also known as Airai, will replace Polaris around 3000, followed by Iota Cephei in 5200. Polaris will again become the Pole star in 27.800 after it finishes the 25,770 year cycle.
The name of the north star is Polaris. As the brightest star in the constellation of Ursa Minor it is also called alpha Ursae Minoris. It is actually a multiple star comprised of Polaris Aa, Polaris Ab and Polaris B.
The common name for Polaris, the North Star, is simply "Polaris."
No, Rigel is not the closest star to Polaris (the North Star). Rigel is a bright star in the constellation Orion, while Polaris is located in the constellation Ursa Minor. The closest star to Polaris is Urodelus, also known as "Polaris Australis."
